CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 658,776, dated October 2, 1900.

v Application filed May 9, 1898. Serial No- 680,220. (N0 model.)

To alt whom it may concern.-

Be it known that 1, JOHN HODGE,a citizen of the United States, residing at Topeka, in the county of Shawnee, State of Kansas, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification, reference being bad to the accompanying drawings.

My invention relates to improvements in car-roofs in which metal sheets are used, supported by the frame of the car; and it has for its object to provide certain improvements in roofs of this character by which the metal sheets, as well as the frame of the roof, may be strengthened and the efficiency of the roof increased.

In the drawings, Figure l is a perspective view of a part of a roof, certain portions being broken away. Fig. 2 is a cross-section of a part of a roof. 7 Fig. 3 is a partial longitudinal section on line 3 3 of Fig. 2, and Fig. 4 is a diagrammatic view showing the arrangement of the roofing-plates.

Referring to the drawings, 5 indicates the ridge-pole, which extends longitudinally the full length of the car and is grooved to receive the ends of the metal sheets and mortised to receive the ends of the false carlines and the inner ends of the metal sheets and caps hereinafter described.

6 indicates one of the side plates of the car, and 7 a purlin, the latter extending the length of the car between the ridge-pole and side plate and acting as a support for the metal sheets 8 at their centers. The purlin 7 also supports the false carlines 9, which extend transversely of the car-roof, as shown in Figs. 1 and 3, their inner ends being mortised in the ridge-pole, as shown, and their outer ends secured to the side plates 6. The false carlines are also secured to the purlin 7.

As illustrated in Figs. 1, 3, and 4, the roofing -plates 8 are provided with upturned edges 10, and said edges are in turn provided with flanges 11, arranged at right angles thereto. The flanges 11 of the roofing-plates are adapted to rest upon the false carlines 9, as shown in Fig. 3, and when in position the roofing-plates 8 rest upon the purlin '7 and carlines 12.

13 indicates U-shaped metal caps, which are adapted to fit over the false carlines 9 and the edges of the roofing-plates 8, as shown in Figs. 3-and 4, the downturned edges 14 of the caps 13 fitting closely against the upturned edges 10 of the roofing-plates. By this construction a tight connection is made between adjacent sheets, effectually preventing leakage. Both the caps 13 and roofingplates 8 may be removed and-replaced when desired by sliding them off by an endwise movement. The roofing-plates are normally held in place by grooved stop-blocks 15, as shown in Fig. 1. The caps are held in place by spikes 16 or other suitable devices, which secure them to the side plates and purlins. When it is desired to remove the caps, the spikes must be withdrawn. If desired, stopblocks may be used instead of spikes, so that the caps may be withdrawn more readily.

The metal roof is covered bya wooden roof 17 in the usual way.

That which I claim as my invention, and desire to secure by Letters Patent, is

1. In a car-roof, the combination with the ridge pole having longitudinally extending side grooves therein and mortises arranged at intervals along its sides, of false carlines fitting in said mortises at one end, roofingplates, whose inner ends fit in said grooves, the said plates having upturned side edges and outwardly-extending flanges, the latter resting upon said false carlines, and capplates embracing said false carlines and the upturned edges of said roofing-plates, substantially as described.

2. In a car-roof, the combination with the ridge pole having. longitudinally extending side grooves therein and mortises arranged at intervals along its sides, the upper side plates of the car, and intermediate purlins, of false carlines fitting in said mortises at one end, resting upon said side plates at the other end and supported by said purlins at intermediate points, roofing-plates whose inner ends fit in said grooves, whose outer ends rest upon said side plates and whose intermediate portions rest upon said purlins, the said plates having upturned side edges and outwardly-extending flanges, the latter resting upon said false carlines, and cap-plates embracing said false carlines and the upturned edges of said roofing-plates, substantially as described.
